摘要：

We report new satellite retrievals of an aerosol particle size index, Angstrom exponent, along with aerosol optical thickness, obtained from a two channel algorithm for NOAA/AVHRR and ADEOS/OCTS satellite-borne radiometers. The results show characteristic features of the global aerosol size index on global scale. Small aerosol particles were detected in fairly large-scale areas around mid-latitude industrial regions and tropical biomass burning regions, whereas large aerosol particles were detected over most of the ocean area,and over subtropical arid areas.
